Adjustable dumbbell with an orientation feature

Abstract

A selectable weight dumbbell system may include a base and a dumbbell. The base may include one or more weight receiving spaces defined by the base's walls and floor. The dumbbell may include a handle and one or more selectively removable weights. The weights may be removably positionable in the weight receiving spaces. A weight and the base may form an orientation feature or key between the weight and the base that compels the weight to be positioned in said one of the weight receiving spaces in an orientation for selective engagement with the handle. The orientation feature or key may include an orientation element, such as a protrusion or the like, and an orientation receiving element, such as a groove or the like. The orientation element may extend from the weight or the base. The orientation receiving element may be defined in the weight or the base.

1 . A selectable weight dumbbell system comprising:
 a base including a plurality of weight receiving spaces;   a dumbbell including a handle and a plurality of selectively removable weights;   each of said plurality of weights removably positionable in one of said plurality of weight receiving spaces; and   each of said plurality of weights and said base forming an orientation key between said weight and said base that compels said weight to be positioned in said one of said plurality of weight receiving spaces in an orientation for selective operative engagement with said handle.   
     
     
         2 . The selectable weight dumbbell system of  claim 1 , wherein said orientation key includes an orientation element extending from a wall of said weight and an orientation receiving element formed on a wall defining said one of said plurality of weight receiving spaces. 
     
     
         3 . The selectable weight dumbbell system of  claim 2 , wherein said orientation element comprises a protrusion and said orientation receiving element comprises a groove. 
     
     
         4 . The selectable weight dumbbell system of  claim 1 , wherein said orientation key includes an orientation element positioned on a floor of said base proximate said one of said plurality of weight receiving spaces and a corresponding orientation element formed on a periphery of said weight. 
     
     
         5 . The selectable weight dumbbell system of  claim 4 , wherein said orientation element comprises a protrusion and said orientation receiving element comprises a recess. 
     
     
         6 . A selectable weight dumbbell system comprising:
 a base including a plurality of weight receiving spaces;   a dumbbell including a handle and a plurality of selectively removable weights;   each of said plurality of weights removably positionable in one of said plurality of weight receiving spaces; and   a means for orientating said plurality of weights to compel each of said plurality of weights to be positioned in said one of said plurality of weight receiving spaces in an orientation for selective operative engagement with the handle.   
     
     
         7 . The selectable weight dumbbell system of  claim 6 , wherein said means for orientating comprises protrusions extending from said plurality of weights and grooves formed in walls of said base. 
     
     
         8 . The selectable weight dumbbell system of  claim 6 , wherein said means for orientating comprises recesses defined in said plurality of weights and protrusions extending from said base. 
     
     
         9 . A selectable weight dumbbell system comprising:
 a base including a weight receiving space;   a dumbbell including a handle and a weight selectively operatively engageable with the handle;   the weight removably positionable in the weight receiving space; and   an orientation feature that compels the weight to be received in the weight receiving space in an orientation for selective operative engagement with the handle.   
     
     
         10 . The selectable weight dumbbell system of  claim 9 , wherein the orientation feature comprises an orientation element extending from a wall of the weight and an orientation receiving element formed in a wall of the base. 
     
     
         11 . The selectable weight dumbbell system of  claim 10 , wherein the wall defines a boundary of the weight receiving space. 
     
     
         12 . The selectable weight dumbbell system of  claim 10 , wherein the orientation element comprises a key and the orientation receiving element comprises a groove. 
     
     
         13 . The selectable weight dumbbell system of  claim 12 , wherein the key comprises a protrusion. 
     
     
         14 . The selectable weight dumbbell system of  claim 10 , wherein the weight includes a weight engagement feature. 
     
     
         15 . The selectable weight dumbbell system of  claim 14 , wherein the weight engagement feature vertically aligns with the orientation element. 
     
     
         16 . The selectable weight dumbbell system of  claim 14 , wherein the weight engagement features extends from the wall of the weight. 
     
     
         17 . The selectable weight dumbbell system of  claim 9 , wherein the orientation feature comprises an orientation receiving element defined in the weight and an orientation element extending from the base. 
     
     
         18 . The selectable weight dumbbell system of  claim 17 , wherein the orientation element extends from a floor of the base. 
     
     
         19 . The selectable weight dumbbell system of  claim 17 , wherein the orientation receiving element comprises a recess and the orientation element comprises a key. 
     
     
         20 . The selectable weight dumbbell system of  claim 18 , wherein said key comprises a protrusion.
